driveshaft question- transmission swap

[steeeeeve]

Hi Fellas,
1968 c10

Bagged- not C notch

I'm finally having my th400 swapped to a 700r4

My current set up is a 2 piece driveshaft with a slip rear driveshaft.

I have an extra 1 piece driveshaft I could swap to. It has a stock yoke. Should I

a) modify (cut) my 2 piece and go with that?
b) go with a 1 piece and use an 8" slip yoke
or
c) go with 1 piece and keep the stock yoke?


truck is at the shop so I need to make a decision pretty quick,

thanks guys!
